I like this restaurant because of its view on the Eiffel tower. Either on the terrace or inside at some of the tables, you can see the iron lady in front of you during dinner. I recommend it for a romantic dinner. The glittering tower on the exact hours is simply amazing and magic.
Yes, it is a bit expensive. A full meal will always go over 50 EUR per person and a light dinner will easily reach 40. You can also go there for a night drink in the terrace or a coffee on a Saturday or Sunday afternoon. The view is worth it; it is simply the best view of the tower you can get in town.
